NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 642,999, dated February6, 1900.

Application filed December '7, 1899. $erial No. 739,520. (No model.)

To all whom it may concern:

Be it known that I, CHARLES D. ONEIL, a citizen of the United States,residing at Charleston, in the county of Kanawha and- State of WestVirginia, have invented certain new and useful Improvements inNut-Locks; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to a nut-lock.

The object of the invention is to provide a simple, durable, andinexpensive device of this character for locking nuts against accidentaldisplacement from their bolts and at the same time permitting of theremoval of the nut when occasion requires.

To this end the invention consists in certain features of constructionand combination of parts,which,will be hereinafterfully described andclaimed.

In the accompanying drawings, Figure 1 is a perspective view of myimproved nut-lock. Fig. 2 is a longitudinal sectional view. Fig. 3 is across-sectional view. Fig. 4 is a detail perspective view of thelocking-wedge. Fig. 5 is a similar view of the flanged plate.

In the drawings the same reference characters indicate the same parts-ofthe invention.

1 denotes a piece of material through which the bolt 2 extends. This maybe a fish-plate or a railroad-rail or may be a part of a woodenstructure.

3 denotes the flanged plate, which is provided with a central aperture 4to receive the bolt 2 and with a penetrating tongue 5 to engage therecess in the piece 1 and prevent rotation of the plate about the bolt.The side flanges of the plate converge from the upper edge of the plateto the lower edge and receive the tapering edges 6 of the wedgedlocking-plate 7, which is provided with a central recess 8, havingflanged edges 9 to embrace the sides of the nut 10. The upper end of thewedge-plate may be also flanged and is adapted to be engaged by a lip11, formed on the upper edge of the flanged plate, so that thewedge-plate will not accidentally withdraw from its position between theside flanges of the plate.

In use after the bolt has been inserted through the piece 1 and thecentral aperture of the flanged plate and the pentrating lip' engagedwith the recess in the part 1 the nut is screwed home upon the bolt. TheWedgeplate is now drivendownwardly between the side flanges of theflanged plate, with the flanges of said wedge-plate engaging the sidesof the nut. The lip 11 at the upper end of the flanged plate is now bentover the upper edge of the wedge-plate, and in this position the Wedgeis firmly and securely locked to the nut and the nut prevented fromturning.

When it is desired to remove the bolt, the lip 11 is forced back todisengage it from the upper edge of the wedge-plate, which may now bewithdrawn to permit of the unscrewing of the nut from the bolt.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages of myinvention will be readily apparent with out requiring an extendedexplanation. It will be seen that the device is simple, that itsconstruction permits of its manufacture at small cost, and that it isexceedingly well adapted for the purpose for which it is designed, andit will of course be understood that various changes in the form,proportion, and the minor details of construction may be resorted towithout departing from the principle or sacrificing any of theadvantages of this invention.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is

The combination with a flanged plate, the flanges of which converge fromthe upper to the lower edge, said plate being providedwith an apertureand with two lips, one struck from the body of the plate withinitsmarginal edges, and the other formed on one of the edges of the plate;of a locking-wedge having a recess formed in one of its edges andextending up a distance toward its opposite edge, the walls of saidrecess being formed with marginal flanges, substantially as and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- CHARLES D. ONEIL.
